-------------------------------------+-------------------------
 Attached is a way to test for unprotected references to C99 math macros on
 platforms where they are implemented as functions.  Adding this to a
 released header would make it convenient to test new code for any
 omissions.

 I used this to find the problems submitted in ticket #8732.

 With, for example, fpclassify redefined, any unprotected references will
 expand out to a syntax error.

 {{{
 #define fpclassify(x) (another_fpclassify(x))
 bad_call = boost::math::fpclassify(arg);
 }}}

 becomes

 {{{
 bad_call = boost::math::(another_flclassify(arg));
 }}}
